C#DataGridView专注于最后的记录

Question

我有一个DataGridView,我从键盘模拟设备扫描检查.

当keypreview打开并且我正在等待输入时,用户无法输入任何内容,否则它会被我的方法抓取以通过检查读取器读取输入.这一切都很好.

在扫描之后,我将向datagridview添加一行,该行将被放在最后.

如何在每次添加后将datagridview滚动到底部？我结束了几百次检查,它位于顶部.因此,每次扫描时,他们都不知道扫描的是什么.

这是我创建行的方法:

private void Timer1Tick(object sender, EventArgs e)
{
  _secondswaited += 1;
  if (_secondswaited == SecondsToWait)
  {
    timer1.Enabled = false;

    var psc = new ParseScannedCheckNumbers();
    if (psc.ParseCheck(_checkData))
    {
      label_Status.Text = @"Scan Next Check";

      var ct = checkTrans.IndividualCheck.NewIndividualCheckRow();
      ct.Date = DateTime.Now.ToShortDateString();
      ct.AccountNumber = GetAccountNumber(psc.BankAccountNumber);
      ct.Name = GetAccountName(ct.AccountNumber);
      ct.AccountBalance = GetAccountBalance(ct.AccountNumber);
      //ct.CheckAmount = 0;
      ct.BankRoutingNumber = psc.BankRoutingNumber;
      ct.BankAccountNumber = psc.BankAccountNumber;
      ct.CheckNumber = psc.CheckNumber;
      ct.Status = "Entered";
      checkTrans.IndividualCheck.Rows.Add(ct);
      var dgvcount = dgv_Checks.Rows.Count;
      **dgv_Checks.Rows[dgvcount - 1].Selected = true;**       
    }
    else
    {
      label_Status.Text = @"Scan failed. Rescan check.";
    }
    _checkData = string.Empty;
    _secondswaited = 0;

    var rs = new Registry.RegistrySettings();
    if (!rs.ScanChecksContinuous)
    {
      StopScanning();
      label_Status.Text = @"Success!";
      EditLastRowEntered();
    }

    label_ChecksScanned.Text = (dgv_Checks.RowCount - 1).ToString();
  }
}

粗体部分是我试图移动到最后一行的地方,没有成功.

谢谢!

Answer 1

我将使用DataGridView.CurrentCell属性.尝试使用此代替您遇到问题的行:

dgv_Checks.CurrentCell = dgv_Checks.Rows[dgvcount - 1].Cells[0];

Answer 2

我认为您需要做的是检查该行是否正在显示。进而

用粗体替换该行

if(dgv_Checks.Rows[dgvcount - 1].Displayed == false)
{

dgv_Checks.FirstDisplayedScrollingRowIndex = dgvcount - 1;

}
